An air capacitor has an area of `1,000 cm^2` and the two plates are 4 mm apart. It is connected in series with another capacitor having a plate ares of `20 cm^2`, the plates being separated by a dielectric 0.1 mm thick having dielectric constant o 2.5 . If the potential difference across the second capacitor is 100 V, find the voltage applied across the series combination.
